<First embodiment>
An information processing system according to the first embodiment of the present invention will be described with reference to FIG. FIG. 1 shows an example of an information processing system according to the first embodiment.

The information processing system according to the first embodiment includes a plurality of terminal devices 10 and a server 12 as an example. For example, each terminal device 10 and server 12 have a function of communicating with other devices via a communication path N such as the Internet. Of course, the terminal device 10 and the server 12 may communicate with other devices via different communication routes without using the communication route N, or may communicate directly with other devices. In the example shown in FIG. 1, three terminal devices 10 are included in the information processing system, but one or more terminal devices 10 may be included in the information processing system.

The terminal device 10 is a device such as a personal computer (PC), a tablet PC, a smart phone, a mobile phone, etc., and has a function of transmitting and receiving data to and from another device. The terminal device 10 may be a wearable terminal (wristwatch type terminal, wristband type terminal, eyeglass type terminal, ring type terminal, contact lens type terminal, implantable terminal, hearable terminal, etc.). Moreover, the terminal device 10 may have a flexible display as a display device. Examples of flexible displays include organic electroluminescence displays (flexible organic EL displays), electronic paper displays, flexible liquid crystal displays, and the like. A flexible display employing a display method other than these may be used. A flexible display is a display whose display portion can be flexibly deformed, for example, a display that can be bent, folded, rolled, twisted, and stretched. The terminal device 10 as a whole may be configured with a flexible display, or the flexible display and other configurations may be functionally or physically separated.

The server 12 is a device that manages data and user information. For example, the server 12 has a function of providing social networking services (SNS) to users. By using the SNS provided by the server 12, the terminal device 10 can transmit and receive information (for example, character strings, still images, moving images, sounds, etc.) to and from other terminal devices 10 using the SNS. It can be carried out. The SNS allows dialogue (exchange of information) in dialogue group units, and the server 12 manages the dialogue in each dialogue group. One or more users (also called speakers) can participate in each dialogue group, and information can be transmitted and received between terminal devices 10 of multiple users belonging to the same dialogue group. For example, when multiple users are logged into the same dialogue group, information is transmitted and received between the terminal devices 10 of the multiple users.

The configuration of the terminal device 10 will be described in detail below with reference to FIG.

The communication unit 14 is a communication interface and has a function of transmitting data to other devices and a function of receiving data from other devices. The communication unit 14 may be a communication interface having a wireless communication function or a communication interface having a wired communication function. The communication unit 14, for example, supports one or more types of communication methods, and may communicate with the communication partner according to a communication method suitable for the communication partner (i.e., a communication method supported by the communication partner). . Communication methods include, for example, infrared communication, visible light communication, Wi-Fi (registered trademark) communication, close proximity wireless communication (for example, NFC (Near Field Communication), etc.), and the like. Felica (registered trademark), Bluetooth (registered trademark), RFID (Radio Frequency Identifier), and the like are used as close proximity wireless communication. Of course, another type of wireless communication may be used as close proximity wireless communication. The communication unit 14 may switch the communication method and frequency band according to the communication partner, or may switch the communication method and frequency band according to the surrounding environment.

The UI section 16 is a user interface section and includes a display section and an operation section. The display unit is, for example, a display device such as a liquid crystal display. The display may be a flexible display. The operation unit is, for example, an input device such as a touch panel or keyboard. A user interface that serves as both a display unit and an operation unit (for example, includes a touch-type display and a device that electronically displays a keyboard or the like on the display) may be used. The UI unit 16 may also include a sound collecting unit such as a microphone and a sound generating unit such as a speaker. In this case, the information may be input to the terminal device 10 by voice input, or the information may be issued by voice.

The storage unit 18 is a storage device such as a hard disk or a memory (such as an SSD). The storage unit 18 stores, for example, various data, various programs (for example, an OS (Operating System), various application programs (application software), etc.), and information indicating the address of another terminal device 10 (terminal address information). , information indicating the address of the server 12 (server address information), and the like are stored. They may be stored in separate storage devices or may be stored in one storage device. For example, an SNS application program for using the SNS provided by the server 12 is stored in the storage unit 18, and the SNS can be used by executing the SNS application program. Information transmitted or received by the terminal device 10 using the SNS may be stored in the storage unit 18 .

The detection unit 20 has a function of detecting a user's operation. The user's operation is, for example, the user's gesture motion, voice, or the like. Gesture motions include, for example, finger movements, hand movements, arm movements, neck movements, leg movements, eyeball movements, eyelid movements, upper body movements, lower body movements, whole body movements, and facial movements. These include changes in facial expressions, mouth movements, and the like. For example, the detection unit 20 detects a user's operation using a sensor. As the sensor, for example, a sensor that detects physical contact with the display section of the UI section 16 is used. Examples of such sensors include a pressure sensor that detects pressure on the display, a capacitance sensor that detects changes in capacitance, a temperature sensor that detects changes in temperature due to contact, and a humidity sensor that detects changes in humidity. etc. are used. A camera may also be used as the sensor. By using a camera, physical contact with the display unit may be detected, or a user's operation without physical contact with the display unit may be detected. When a flexible display is used as the display unit, a pressure sensor, an acceleration sensor, a gyro sensor, or the like is used as the sensor. Changes, temperature, humidity, acceleration, orientation, etc. may be detected. Note that the user's operation may be detected by an external sensor provided in a location or device other than the terminal device 10 . In this case, information indicating the detection result is transmitted from the sensor to the terminal device 10, and the control section 22 receives the information. If an external sensor is used, the terminal device 10 need not have a sensor. A sound collecting device such as a microphone may be used as the sensor, and the detection unit 20 may detect the user's voice.

The control unit 22 has a function of controlling the operation of each unit of the terminal device 10 . For example, the control unit 22 executes various programs, controls communication by the communication unit 14, controls notification of information using the UI unit 16 (for example, display and audio output), and controls input using the UI unit 16. Receive information, etc. For example, the SNS provided by the server 12 can be used by the control unit 22 executing an SNS application program. Also, the control unit 22 includes a display control unit 24 .

The display control unit 24 has a function of controlling display of various information. For example, when an SNS is used, the display control unit 24 causes the display unit of the UI unit 16 to display information (character strings, images, etc.) transmitted or received using the SNS. Audio information transmitted or received using the SNS may be output from a speaker or the like. Further, when the user performs an operation to change the current dialogue partner in the SNS to another dialogue partner, and the detection unit 20 detects the operation, the display control unit 24 displays on the display unit The screen is changed to a screen for interacting with the other interaction partner. Processing by the display control unit 24 will be described later in detail.

The configuration of the server 12 will be described in detail below with reference to FIG. FIG. 3 shows the configuration of the server 12. As shown in FIG.

The communication unit 26 is a communication interface and has a function of transmitting data to other devices and a function of receiving data from other devices. The communication unit 26 may be a communication interface having a wireless communication function, or may be a communication interface having a wired communication function.

The storage unit 28 is a storage device such as a hard disk or a memory (such as an SSD). The storage unit 28 stores, for example, various data, various programs, terminal address information of the terminal device 10, server address information of the server 12, and the like. Of course, they may be stored in separate storage devices or in one storage device. For example, information transmitted by the terminal device 10 using SNS may be stored in the storage unit 28 .

The control unit 30 controls operations of each unit of the server 12 . For example, the control section 30 controls communication by the communication section 26 . The control unit 30 also includes a service providing unit 32 .

The service providing unit 32 has a function of providing SNS to the terminal device 10 . For example, the service providing unit 32 transmits information (for example, character strings, images, voice information, etc.) sent from the terminal device 10 to the server 12 using the SNS to other terminal devices 10 using the SNS. Send to The service providing unit 32 also has a function of controlling dialogue (exchange of information) in units of dialogue groups. Specifically, the service providing unit 32 controls transmission and reception of information between the terminal devices 10 of multiple users logged in to the same dialogue group. In other words, the service providing unit 32 transmits information transmitted from the terminal device 10 of the user logged in to a dialogue group to the server 12 to the terminal device 10 of another user logged into the dialogue group. For example, the service providing unit 32 stores, for each dialogue group, dialogue group identification information for identifying the dialogue group and identification information (for example, user account User identification information such as information, terminal identification information, etc.) are associated with each other, and the information is managed. By referring to the managed information, the service providing unit 32 identifies users and terminal devices 10 logging in to each dialogue group, and controls transmission and reception of information among the plurality of terminal devices 10 .

The transmission and reception of information using the SNS may be performed via the server 12, or may be performed directly between the plurality of terminal devices 10 without via the server 12 (without via other devices). ), or indirectly (via another device).

Hereinafter, the operation of the terminal device 10 will be described in detail with specific examples.

For example, users A, B, and C belong to dialogue group 1, users A, D, and E belong to dialogue group 2, and dialogue groups 1 and 2 are both engaged in dialogue using SNS. shall be For example, assume that users A, B, and C have logged into dialogue group 1 and are sending and receiving messages, and users A, D, and E have logged into dialogue group 2 and are sending and receiving messages.

Each user uses the SNS using his or her own terminal device 10 . Of course, the same terminal device 10 may be shared by a plurality of users if the same terminal device 10 is capable of switching between user accounts, or if it is possible to distinguish between users and transmit and receive information.

Hereinafter, for convenience of explanation, the terminal device 10 used by user A will be referred to as “terminal device 10A”, the terminal device 10 used by user B will be referred to as “terminal device 10B”, and the terminal device 10 used by user C will be referred to as “terminal device 10B”. The terminal device 10 used by user D is called "terminal device 10C", the terminal device 10 used by user E is called "terminal device 10E".

For example, a user may send information to another user such that the user may form a dialogue group, or new users may join or be invited to an already formed dialogue group. , the new user may be added to the dialogue group. Also, a dialogue group may be formed in advance. These dialogue groups are managed by the service provider 32 of the server 12 .

For example, users A, B, and C use their own terminal devices 10 to activate SNS application programs, and log in to the dialogue group 1 formed by the SNS provided by the service providing unit 32 . In order to log in, information for identifying the user (eg, user ID, name, etc.) or authentication information (eg, password, biometric information of the user, etc.) may be used. When the user A instructs transmission of a message to the dialogue group 1, the terminal device 10A transmits the message to the server 12. FIG. The service providing unit 32 of the server 12 receives the message transmitted from the terminal device 10A, and transmits the message to the user B's terminal device 10B and the user C's terminal device 10C. The terminal address information of each of the terminal devices 10B and 10C may be sent from the terminal device 10A to the server 12 or stored in the server 12 in advance. The service providing unit 32 identifies the terminal devices 10B and 10C using the terminal address information, and transmits a message from the user A to the terminal devices 10B and 10C. The display control unit 24 of the terminal device 10B causes the display unit of the UI unit 16 to display the message from the terminal device 10A. The same processing is performed in the terminal device 10C.

Note that the service providing unit 32 may transmit a confirmation message indicating that the message has been sent from the user A to the terminal devices 10B and 10C. In this case, the display control unit 24 of the terminal device 10B displays the confirmation message on the display unit. When the user B uses the UI unit 16 to instruct acquisition of a message from the user A, the terminal device 10B transmits an acquisition request for the message to the server 12 . The service providing unit 32 transmits the message from the user A to the terminal device 10B in response to the acquisition request. The display control unit 24 of the terminal device 10B displays the message on the display unit. The same processing is performed in the terminal device 10C.

Note that if the user B has not logged in to the dialogue group 1 or if the SNS application has not been activated on the terminal device 10B, the display control unit 24 of the terminal device 10B causes the display unit to display the confirmation message. may For example, the display control unit 24 causes the display unit to display an image (e.g., icon) representing the SNS application program, and associates the image with a confirmation message (e.g., the number of messages that have not been obtained or read by user B). display on the display. When the user B logs in to the dialogue group 1, or when the SNS application program is started on the terminal device 10B, the terminal device 10B transmits a request for obtaining the message of the user A to the server 12. FIG. The service providing unit 32 transmits the message to the terminal device 10B in response to the acquisition request. The display control unit 24 of the terminal device 10B displays the message on the display unit. The same process as described above is performed even when the user C has not logged in to the dialogue group 1 or when the SNS application program has not been activated on the terminal device 10C.

When users B and C send messages, the same process as when user A sends a message is performed. The same processing is also executed for dialogue group 2 . Each user may log into the dialogue group at a later time or log out of the dialogue group along the way.

A screen displayed on the terminal device 10 when using the SNS will be described with reference to FIG. FIG. 4 shows an example of a screen displayed on the terminal device 10A used by the user A. As shown in FIG. The display control unit 24 of the terminal device 10A causes the display unit of the UI unit 16 to display a screen 34, and causes the screen 34 to display various information. The screen 34 is an interface (dialogue screen) for interacting with other users (speakers). Information (for example, character strings, images, etc.) input by each user is displayed on the screen 34 . The dialogue between multiple users may be a so-called chat-type dialogue (that is, a real-time dialogue, in other words, a dialogue progressing while each user speaks). For example, when the control unit 22 of the terminal device 10A executes the SNS application program, the display control unit 24 causes the display unit of the UI unit 16 to display the screen 34 for interacting using the SNS. By executing the SNS application program, it may be possible to use an Internet telephone function, etc., in addition to the chat function.

The screen 34 is a screen on which the content of dialogue among the users A, B, and C logged in to the dialogue group 1 is displayed. Dialogue group 1 being displayed is the current dialogue partner (dialogue group) for user A, and users B and C are the current speakers for user A.

The display control unit 24 causes the screen 34 to display an image 36 associated with the user A, an image 38 associated with the user B, and an image 40 associated with the user C. An image 36 is an image for identifying user A, an image 38 is an image for identifying user B, and an image 40 is an image for identifying user C. FIG. A character string indicating the user A (for example, a character string for identifying the user such as a name, user ID, handle name, nickname, etc.) may be displayed instead of the image 36 or together with the image 36 . The same is true for the images 38,40. An image 36 associated with user A is displayed in a region assigned to the user who uses the terminal device 10A within the screen 34, and an image 38 associated with user B and an image 40 associated with user C are displayed within the screen 34. in the area assigned to other users.

From then on, the users A, B, and C have a dialogue. Each user may input the utterance content by operating the UI unit 16 of his or her own terminal device 10 to input a character string, an image, or the like, or may input the utterance content by voice. Also, the content of each user's utterance may be output as voice. The input speech content is transmitted to the terminal device 10 of another user according to the user's instruction. Each statement is displayed in chronological order according to the date and time when it was sent. As the dialogue progresses on the screen 34, the screen 34 scrolls, the past utterance contents that cannot be displayed on the screen 34 disappear from the screen 34, and the latest utterance contents and the most recent utterance contents are displayed on the screen 34. be.

The utterance content 42 is the utterance content (for example, message) transmitted by the user B using the terminal device 10B. The statement content 42 is transmitted from the terminal device 10B to the server 12, and is transmitted from the server 12 to the terminal devices 10A and 10C belonging to the dialogue group 1 by the service providing unit 32. FIG. Of course, the statement content 42 may be transmitted from the terminal device 10B to the terminal devices 10A and 10C without going through the server 12 . The utterance content 42 is displayed on the screen 34 in association with the user B's image 38 . The utterance content 42 is also displayed as user B's utterance content on the terminal devices 10B and 10C. The utterance content 44 is the utterance content transmitted by the user A using the terminal device 10A, and is displayed on the screen 34 in association with the image 36 of the user A. Displayed as speech. The utterance content 46 is the utterance content transmitted by the user C using the terminal device 10C, and is displayed on the screen 34 in association with the image 40 of the user C. Displayed as speech. The statement content 48 is the statement content transmitted by the user A. FIG. In the example shown in FIG. 4, each statement content is transmitted in the order of statement content 42, 44, 46, 48, and the statement content 42, 44, 46, 48 is displayed in chronological order according to the date and time of transmission. It is The same applies to the contents of the subsequent statements.

Also, information indicating the time (for example, time or date) at which each message was transmitted may be displayed on the screen 34 . For example, the screen 34 displays a character string indicating a date (for example, today's date, November 2nd). Messages displayed below the display position of the character string indicating that date are messages sent on or after that date, and messages displayed above that display position are those sent on that date. This is the statement content sent on the date before. For example, the statement content 42 was transmitted by the user B at 16:00 on November 2nd, and information indicating the time is displayed in association with the statement content 42 . Information indicating the time is similarly displayed for other utterance contents. Of course, the information indicating the time and date may not be displayed.

Also, the read and unread status of the statement content may be managed. Here, read messages and unread messages will be explained. A read message is statement content that has been read by another user, and an unread message is statement content that has not been read by another user. For example, when a message (statement content) sent by user A to dialogue group 1 is read by another user (for example, user B or user C), read information indicating that the message has been read is The message is transmitted from the terminal device 10 of the user who read the message to the terminal device 10A. For example, when an SNS application program is executed in another user's terminal device 10 and a message of user A is displayed on a screen for interaction (for example, a screen corresponding to screen 34), the message is displayed by the other user treated as having been read by In this case, the read information is transmitted from the terminal device 10 of the other user to the terminal device 10A. Of course, when another user designates the message of user A on his terminal device 10, designates the message and displays the message in another window (separate screen), When the information transmission instruction is given, the read information may be transmitted from the terminal device 10 of the other user to the terminal device 10A. As another example, when a confirmation message indicating that User A's message has been sent is displayed on the display unit of another user's terminal device 10, and the other user gives an instruction to display User A's message Alternatively, when the message is actually displayed, the already-read information may be transmitted from the other user's terminal device 10 to the terminal device 10A.

When read information is transmitted from another terminal device 10 to the terminal device 10A, the display control unit 24 of the terminal device 10A associates the read information (character string, image, etc.) with the message and displays it on the display unit. Let In the example shown in FIG. 4, user A's statement content 44 (message) has been read by another user, and read information (for example, a character string “read”) is displayed in association with the statement content 44. there is For example, already read information is displayed near the statement content 44 . The read information may be displayed in association with the statement content 44 when the statement content 44 has been read by all other users, or may be displayed when the statement content 44 has been read by at least one other user. The reading information may be displayed in association with the utterance content 44 .

The statement content associated with read information corresponds to a read message, and the message not associated with read information corresponds to an unread message. Since read information (for example, the character string "read") is not displayed in association with the statement content 48 of the user A, the statement content 48 corresponds to an unread message.

The display control unit 24 may display unread information indicating that the message has not been read by another user on the screen 34 in association with the unread message. For example, unread information may be displayed in association with the statement content 48 . Moreover, both read information and unread information may be displayed, or either one may be displayed.

In the example shown in FIG. 4, the already-read information is displayed as a character string in association with the content of the statement, but a method other than the method of using the character string may be used as a method of expressing the already-read information. For example, the display control unit 24 may change the mode of expression between read messages and unread messages. Specifically, the display control unit 24 may express the character string included in the unread message using a specific font, express the character string in a specific color, or express the character string may be expressed in bold, the display frame of the unread message may be decorated, or the unread message may be highlighted. By doing so, read messages and unread messages are displayed separately from each other. In the example shown in FIG. 4, the statement content 44 is a read message, and the statement content 48 is an unread message. Of course, the display control unit 24 may apply the above processing to read messages and not apply the above processing to unread messages. Further, the display control unit 24 may display the read information and the unread information and execute the above process.

The concepts of read messages and unread messages are not limited to the above concepts. For example, if user A reads a message sent by another user, the message is treated as a read message, and if user A has not read a message sent by another user, the message is treated as an unread message. may be broken. For example, if a message sent by user B to dialogue group 1 has not been read by user A, the message corresponds to an unread message for user A. When the user A designates a message of the user B on the terminal device 10A, designates the message and displays the message in another window (separate screen), or gives an instruction to send the read information. If so, the control unit 22 of the terminal device 10A determines that the user A has read the message. As another example, a confirmation message indicating that user B's message has been transmitted is displayed on the display unit of the terminal device 10A, and when user A gives an instruction to display user B's message, or when the message is The control unit 22 may determine that the message has been read by the user A when it is actually displayed. Further, when the message of user B is displayed on the screen 34, the control unit 22 may determine that the message has been read by user A. In such a case, read information is transmitted from the terminal device 10A to the terminal device 10B.

When the control unit 22 of the terminal device 10A determines that the message of another user has been read by the user A, the display control unit 24 of the terminal device 10A associates the read information with the message and displays it on the screen 34. . For example, when it is determined that user B's statement content 42 has been read by user A, the display control unit 24 associates read information (for example, a character string “read”) with the statement content 42 and displays it on the screen 34 . Let The display control unit 24 associates the read message with the read information and does not display or displays it on the screen 34 , and also associates the unread message with unread information (for example, a character string “unread”) and displays it on the screen 34 . You may let In addition, the display control unit 24 may change the mode of expression between the read message and the unread message so that the read message and the unread message are displayed separately.

The read information and unread information about user A's message may be displayed on the screen 34 , and the read information and unread information about other users' messages may be displayed on the screen 34 . It should be noted that read information and unread information may not be displayed.

As described above, while the dialogue content of the dialogue group 1 is displayed on the screen 34, the user A performs an operation to change the current dialogue group to another dialogue group in which the user A is logged in. , the operation is detected by the detection unit 20, the display control unit 24 of the terminal device 10A changes the screen 34 to a screen for interacting with the other interaction group. For example, when the user A performs an operation to move the screen 34 in the direction indicated by the arrow 50 (for example, when performing a flick operation), the display control unit 24 changes the screen 34 to interact with another interaction group. screen. The display control unit 24 may change the screen 34 when the user performs a flick operation upward, downward, leftward, or rightward. The operation for changing the dialogue group may be a gesture operation other than the flick operation, voice input, or a combination of gesture motion and voice.

A screen for interacting with another interaction group will now be described with reference to FIG. FIG. 5 shows an example of the screen. A screen 52 is a screen on which the content of dialogue among the users A, D, and E who are logged in to the dialogue group 2 is displayed. Dialogue group 2 being displayed is the current dialogue partner (dialogue group) for user A, and users D and E are the current speakers for user A.

The display control unit 24 causes the screen 52 to display an image 36 associated with the user A, an image 54 associated with the user D, and an image 56 associated with the user E. An image 54 is an image for identifying user D, and an image 56 is an image for identifying user E. FIG. As with the screen 34, a character string indicating the user may be displayed instead of or together with the image of the user. As with screen 34 , screen 52 may display information indicating the time (for example, time or date) when each message was sent. In the example shown in FIG. 5, the screen 52 displays a character string indicating a date (for example, yesterday's date, November 1st). Messages displayed below the character string display position for that date are messages sent on or after that date, and messages displayed above that display position are those sent from that date. is also the content of the statement sent on the previous date. For example, the statement content 58 is transmitted by the user D at 21:00 on November 1st, and information indicating the time is displayed in association with the statement content 58 . Information indicating the time is similarly displayed for other utterance contents. Also, read information and unread information may be displayed, and their display modes may be different from each other so that unread messages and read messages can be distinguished. In the example shown in FIG. 5, the already-read information is displayed in association with user A's statement content and other user's statement content. The image 36 associated with the user A is displayed in the area assigned to the user who uses the terminal device 10A in the screen 52, and the image 54 associated with the user D and the image 56 associated with the user E are displayed in the screen 52. in the area assigned to other users.

After that, the users A, D, and E have a dialogue. The utterance content of each user is transmitted from the user's own terminal device 10 to the terminal device 10 of another user logged in to the dialogue group 2 and displayed. For example, user D's utterance content 58 is displayed on screen 52 in association with user D's image 54, user A's utterance content 60 is associated with user A's image 36 and displayed on screen 52, user E is displayed on the screen 52 in association with the image 56 of the user E, and utterance content 64 of the user A is displayed in the screen 52 in association with the image 36 . As with the screen 34, each message is displayed in chronological order according to the date and time when it was sent.

As described above, according to the first embodiment, it is possible to change the screen for interacting with the conversation partner by a simple operation (for example, gesture motion or voice). In the above example, the dialog group can be changed by changing the dialog group 1 screen to the dialog group 2 screen by a simple operation.

As a comparative example with respect to the first embodiment, a screen for selecting a dialogue partner (for example, a selection screen displaying a list of dialogue groups) is displayed, and when changing the dialogue partner, the user, on the selection screen, It is conceivable to select a dialogue partner. In this case, screen 34 for interacting with dialog group 1 is changed to screen 52 for interacting with dialog group 2 according to the following procedure. First, while the screen 34 is being displayed, the user operates the UI unit 16 to give an instruction to display a dialogue partner selection screen. A selection screen is displayed instead of the screen 34 according to the display instruction. When the user selects dialogue group 2 as another dialogue partner on the selection screen, screen 52 is displayed instead of the selection screen. As described above, in the comparative example, operations and processes of instructing display of the selection screen, displaying the selection screen, and selecting dialogue group 2 on the selection screen occur. In contrast, according to the first embodiment, it is possible to change the dialog partner and the screen without executing such work or processing.

As another comparative example, it is conceivable to display a pop-up message of another dialogue group, and switch the dialogue partner to the other dialogue group when the user selects the message. In this case as well, the processing and work of displaying and selecting a pop-up message occur. According to this embodiment, it is possible to change the dialog partner and the screen without executing such processing or work.

A list defining the display order of the dialogue groups may be created in advance, and the display control unit 24 may change the screen according to the display order. For example, when the display order is defined in the order of dialogue groups 1, 2, and 3, the display control unit 24 changes the screen in the order of dialogue groups 1, 2, and 3 according to the screen change operation. If a change operation is performed while the screen of dialogue group 3 is being displayed, the display control unit 24 changes the screen of dialogue group 3 to the screen of dialogue group 1 . The display order may be defined by the user or according to the order of the interaction groups that the user has logged into.

Modifications of the first embodiment will be described below.

(Modification 1)
In Modification 1, the display control unit 24 enlarges or reduces the screen being displayed according to the user's operation. For example, as shown in FIG. 6, when the screen 34 is displayed, the user performs an operation (for example, a pinch-out operation) to enlarge the screen 34 as indicated by an arrow 66, and when that operation is detected, The display control unit 24 enlarges the screen 34 . Further, when the user performs an operation of pinching the screen 34 (for example, a pinch-in operation) and the operation is detected, the display control unit 24 reduces the screen 34 . The enlargement operation and reduction operation are, for example, predefined, and the definition may be changed by the user. The screen may be enlarged or reduced by an operation other than the above pinch-out operation or pinch-in operation.

When an enlargement operation or a reduction operation is performed on the screen 34 being displayed, the display control unit 24 interlocks with the operation to create a screen (for example, the screen 52 ) may be enlarged or reduced. In other words, the display control unit 24 synchronizes the enlargement or reduction of the screen between the screen of the dialogue group that is being displayed and the screen of the dialogue group that is not being displayed. The enlargement rate (enlargement amount) or reduction rate (reduction amount) of the screen 52 during non-display may be the same as the enlargement rate (enlargement amount) or reduction rate (reduction amount) of the displayed screen 34, can be different. The setting may be made by the user. When an operation for changing the dialogue group is detected, the display control unit 24 changes the currently displayed screen (for example, the screen 34) to a screen for dialogue with another dialogue group (which reflects the enlargement or reduction). state screen) (for example, screen 52). By doing so, the enlarged or reduced screen is displayed without performing an enlargement operation or a reduction operation on the changed screen, saving the user the trouble of enlarging or reducing the screen.

Of course, when an enlargement operation or a reduction operation is performed on the screen being displayed, the display control unit 24 does not interlock with the operation, but enlarges or reduces only the screen being displayed, and It is not necessary to enlarge or reduce the screen for interacting with the interactive group. Interlocking control (synchronous control) or non-interlocking control (asynchronous control) may be set by the user.

(Modification 2)
Modification 2 will be described with reference to FIGS. 7 and 8. FIG. In Modified Example 2, the display control unit 24 causes the display unit to display information (character strings, images, etc.) that cannot be displayed on the screen by scrolling the displayed screen according to the user's operation. For example, as shown in FIG. 7, when the screen 34 is displayed, the user A performs an operation to scroll the screen 34 as indicated by an arrow 68, and when the operation is detected, the display control unit 24 , scrolls the screen 34 in the direction indicated by the arrow 68 .

When a scrolling operation is performed on the screen being displayed, the display control unit 24 may scroll the screen for interacting with another non-displaying dialogue group in conjunction with the scrolling operation. In other words, the display control unit 24 synchronizes the screen scrolling between the screen of the dialogue group being displayed and the screen of the dialogue group being hidden. FIG. 8 shows a screen 52 for interacting with other interaction groups. Although the screen 52 is not displayed on the display unit, the display control unit 24 scrolls the screen 52 in the direction indicated by the arrow 70 (the same direction as the direction indicated by the arrow 68) in conjunction with the scrolling operation on the screen 34. The amount of scrolling of the screen 52 during non-display may be the same as the amount of scrolling of the screen 34 during display, or may be different. The setting may be made by the user. When an operation for changing the dialogue group is detected, the display control unit 24 changes the currently displayed screen (for example, the screen 34) to a screen for dialogue with another dialogue group (a state in which scrolling is reflected). screen) (for example, screen 52). By doing this, the scrolled screen is displayed without performing a scroll operation on the screen after the change, so that the user can save the time and effort of the scroll operation.

Of course, when a scrolling operation is performed on the screen being displayed, the display control unit 24 scrolls only the screen being displayed without interlocking with the operation, and interacts with other non-displaying dialogue groups. You don't have to scroll the screen for Interlocking control (synchronous control) or non-interlocking control (asynchronous control) may be set by the user.

When a scrolling operation is performed on the screen being displayed, the display control unit 24 scrolls the screen for interacting with another non-displayed dialog group to the position where the unread message is displayed. good.

For example, when a scrolling operation is performed on the screen 34 being displayed, if there is an unread message in the hidden dialogue group 2, the display control unit 24 hides the screen 52 of the dialogue group 2. , scroll to the display position of the unread message. For example, the display control unit 24 scrolls the screen 52 so that the unread message is displayed at a specific position (for example, central position, top, bottom, etc.) of the screen 52 . FIG. 9 shows an example of the screen 52 after scrolling. For example, today (November 2nd), if the message content 72 sent by the user A is in an unread state, the display control unit 24 causes the screen 52 to display the message content 72 at the center position of the screen 52 . to scroll. Of course, the display control unit 24 may scroll the screen 52 so that the statement content 72 is displayed at the top or bottom of the screen 52 . Note that the statement content displayed below the display position of the character string indicating today's date (November 2nd) is the statement content sent after November 2nd, and is above the display position. is the message sent on a date before November 2nd. When there are a plurality of unread messages, the display control unit 24 may scroll the screen 52 to the display position of the unread message sent on the oldest date and time, or display the unread message sent on the latest date and time. You can scroll to the position.

When an operation for changing the dialogue group is detected, the display control unit 24 scrolls the currently displayed screen (for example, screen 34) to a screen for dialogue with another dialogue group (unread message display position). is reflected) (for example, screen 52). By doing this, the unread message is displayed without performing a scroll operation on the screen after the change, and the time and effort of the scroll operation by the user can be reduced. In the example shown in FIG. 9, the statement content 72 is displayed after the screen is changed.

Further, when a scrolling operation is performed on the screen 34 that is being displayed, if there is an unread message that has not been read by the user A in the non-displayed dialogue group 2, the display control unit 24 displays the dialogue group 2 screen 52 is scrolled to the display position of the unread message in a non-display state. By doing this, when the screen 34 being displayed is changed to the screen 52, an unread message (a message that the user A has not read) is displayed without scrolling the screen 52 after the change. , the time and effort of the scrolling operation by the user is reduced.

Further, when there is an unread message in the dialogue group 1 being displayed, the display control unit 24 may scroll the screen 34 to the display position of the unread message according to the scrolling operation on the screen 34 being displayed.

(Modification 3)
In Modified Example 3, when an operation for changing the current dialogue group to another dialogue group is detected, the display control unit 24 changes the screen of the currently displayed dialogue group to that of the other active dialogue group. Prioritize changing to the screen for dialogue. An active dialogue group is, for example, a dialogue group in which another user is logged in, a dialogue group in which the elapsed time from the transmission/reception of the last message is within a predetermined period of time, or the like. For example, when user A logs in to a plurality of dialogue groups and interacts in a plurality of dialogue groups, the display control unit 24 activates the screen of the currently displayed dialogue group according to the screen change operation. to change to a screen for interacting with the dialog group.

On the other hand, the display control unit 24 may exclude the non-active dialogue group (the dialogue group that is not the active dialogue group) from the display target, or may display , a screen for interacting with the inactive interaction group may be displayed on the display.

An active dialogue group is inferred to be more likely to be interacted with by a user than an inactive dialogue group. Therefore, according to Modification 3, the dialog group screens with which the user can interact are preferentially displayed.

(Modification 4)
In Modified Example 4, the display control unit 24 changes the screen according to the priority based on the number of logged-in users in each dialogue group. The control unit 22 determines the priority of each dialogue group based on the number of users (the number of speakers) logging in to each dialogue group. For example, a dialogue group with a greater number of logged-in users has a higher priority. As a specific example, it is assumed that user A has logged into dialogue groups 4, 5, and 6. FIG. Four users including user A are logged into dialogue group 4, five users including user A are logged into dialogue group 5, and user A is logged into dialogue group 6. Assume that six users are logged in, including In this case, the priority of dialogue group 6 is first, the priority of dialogue group 5 is second, and the priority of dialogue group 4 is third. is changed. For example, when a screen change operation is detected while the screen of dialogue group 4 is being displayed, the display control unit 24 causes the screen of dialogue group 4 to interact with dialogue group 6, which has the highest priority. screen. When a screen change operation is detected while the screen of the dialogue group 6 is being displayed, the display control unit 24 changes the screen of the dialogue group 6 to a screen for dialogue with the dialogue group 5 having the second priority. change to When a screen change operation is detected while the screen of dialogue group 5 is being displayed, the display control unit 24 changes the screen of dialogue group 5 to a screen for dialogue with dialogue group 4, which has the third priority. change to The same processing is performed thereafter.

According to Modification 4, the user can change the screen according to the number of logged-in users by a simple operation.

The priority may be changed according to the operation. For example, when a first operation (for example, a rightward flick operation on the screen) is detected, the display control unit 24 changes the screen according to the priority order. When a second operation (for example, a leftward flick operation on the screen) is detected, the display control unit 24 changes the screen according to the order of priority opposite to the order of priority described above. By doing so, the priority can be changed by a simple operation. The first operation and the second operation may be predetermined or may be changed by the user.

Note that when a specific change operation (for example, an upward flick operation on the screen) is detected, the control unit 22 determines that the user A belongs to the logged-in interactive group and the number of logged-in users is the largest. By specifying another dialogue group, the display control unit 24 may change the currently displayed screen to a screen for dialogue with that dialogue group. When a change operation other than a specific change operation is detected, the display control unit 24 changes the screen according to the priority order. By doing so, the user can interact with the interaction group with the largest number of logged-in users by a simple operation. A specific change operation may be predetermined or may be changed by the user.

Modifications 3 and 4 may be combined. For example, when there are a plurality of active dialogue groups, the control unit 22 determines the priority according to the modification 3 for the plurality of dialogue groups, and the display control unit 24 displays the screen according to the priority. change.

(Modification 5)
In Modified Example 5, the display control unit 24 changes the screen according to the priority based on the date and time of transmission of the latest statement content (message) in each dialogue group. For each dialogue group, the control unit 22 specifies the date and time when the latest statement content was transmitted (that is, the transmission date and time of the final message), and based on the transmission date and time of the latest statement content of each dialogue group, Determine your priorities. For example, a dialog group whose transmission date and time of the latest comment content is closer to the current date and time has a higher priority. As a specific example, it is assumed that user A has logged into dialogue groups 4, 5, and 6. FIG. The transmission date and time of the latest statement content in dialogue group 4 is "October 30, 2017, 10:00", and the transmission date and time of the latest statement content in dialogue group 5 is "October 30, 2017, 10:30". It is assumed that the transmission date and time of the latest statement content in the dialogue group 6 is "October 30, 2017, 11:00". In this case, the priority of dialogue group 6 is first, the priority of dialogue group 5 is second, and the priority of dialogue group 4 is third. is changed. That is, the screens are changed in the same order as the order described in the fourth modification.

According to Modified Example 5, the user can change the screen according to the input date and time of the utterance content by a simple operation.

As in Modification 4, the priority may be changed according to the operation. Further, when a specific change operation is detected, the control unit 22 selects the dialogue group in which the user A is logged in and to which the latest statement content is input (that is, the transmission date and time of the last statement content is the current date and time). ), and the display control unit 24 may change the currently displayed screen to a screen for interacting with that dialogue group. When a change operation other than a specific change operation is detected, the display control unit 24 changes the screen according to the priority order. By doing so, the user can interact with the dialogue group to which the latest utterance contents have been input by a simple operation.

Modifications 3 and 5 may be combined. For example, when there are a plurality of active dialogue groups, the control unit 22 determines the priority according to Modification 5 for the plurality of dialogue groups, and the display control unit 24 displays the screen according to the priority. change.

Moreover, modifications 4 and 5 may be combined. That is, the control unit 22 may determine the priority based on the number of logged-in users and the transmission date and time of the latest message content. In this case, the control unit 22 may apply weighting processing to the ranking based on the number of users or the ranking based on the transmission date and time. Modifications 3, 4 and 5 may be combined.

(Modification 6)
In modification 6, the display control unit 24 changes the screen according to the priority based on the number of unread messages in each dialogue group. In the terminal device 10A used by user A, the unread message may be a message of user A that other users have not read, or a message of another user that user A has not read. , or both. The control unit 22 manages the number of unread messages for each dialogue group logged in by user A, and determines the priority of each dialogue group based on the number of unread messages in each dialogue group. For example, dialogue groups with more unread messages have higher priority. As a specific example, it is assumed that user A has logged into dialogue groups 4, 5, and 6. FIG. Assume that the number of unread messages in dialogue group 4 is "4", the number of unread messages in dialogue group 5 is "5", and the number of unread messages in dialogue group 6 is "6". In this case, the priority of dialogue group 6 is first, the priority of dialogue group 5 is second, and the priority of dialogue group 4 is third. is changed. That is, the screens are changed in the same order as the order described in the fourth modification.

According to Modification 6, the user can change the screen according to the number of unread messages by a simple operation.

As in Modification 4, the priority may be changed according to the operation. Further, when a specific change operation is detected, the control unit 22 identifies the dialogue group in which the user A is logged in and has the largest number of unread messages. A screen may be changed to a screen for interacting with that interaction group. When a change operation other than a specific change operation is detected, the display control unit 24 changes the screen according to the priority order. By doing so, the user can interact with the dialog group with the largest number of unread messages by a simple operation. A dialogue group with a smaller number of unread messages may have a higher priority. Such settings may be made by the user.

Modifications 3 and 6 may be combined. For example, when there are a plurality of active dialogue groups, the control unit 22 determines the priority according to Modification 6 for the plurality of dialogue groups, and the display control unit 24 displays the screen according to the priority. change.

Moreover, modifications 4 and 6 may be combined. That is, the control unit 22 may determine the priority based on the number of logged-in users and the number of unread messages. In this case, the control unit 22 may apply weighting processing to the ranking based on the number of users or the ranking based on the number of unread messages. Variations 3, 4 and 6 may be combined.

Moreover, modifications 5 and 6 may be combined. That is, the control unit 22 may determine the priority based on the transmission date and time of the latest message and the number of unread messages. In this case, the control unit 22 may apply a weighting process to the ranking based on the transmission date and time of the latest message or the ranking based on the number of unread messages. Modifications 3, 5 and 6 may be combined, or Modifications 3, 4, 5 and 6 may be combined.

In addition, when the priority is not determined by the above priority determination method, the control unit 22 may determine the priority based on the past display history of each dialogue group. For example, if the transmission date and time of the latest message and the number of unread messages are the same in a plurality of dialogue groups, it is not possible to determine the priority of the plurality of dialogue groups depending on these conditions. In this case, the control unit 22 determines priority based on the display history of each dialogue group. For example, the control unit 22 gives higher priority to a dialogue group whose dialogue content is not displayed for a longer period (non-display period). If the priority cannot be determined even by the non-display period, the control unit 22 may determine the priority based on the name of the dialogue group. For example, the control unit 22 determines the priority according to the Japanese syllabary order or the alphabetical order.

(Modification 7)
In modification 7, when an operation for changing the current dialogue group to another dialogue group is detected, the control unit 22 detects whether one or more users logged in to the current dialogue group are logged in. Another dialogue group is specified, and the display control unit 24 changes the currently displayed screen to a screen for dialogue with the other dialogue group. If there is no such another dialogue group, the display control unit 24 changes the screen according to a predetermined display order.

A specific example will be given for explanation. For example, user A is logged into dialogue groups 1, 2, and 3, and dialogue group 1 is the current dialogue group. In this case, the screen 34 shown in FIG. 4 is displayed on the user A's terminal device 10A. In this state, when the user A performs an operation to change the dialogue group, the control unit 22 selects another dialogue group in which the user A is logged in and at least one of the users B and C Identify another interactive group you are logged into. As described above, users A, B, and C are logged into dialogue group 1, and users A, D, and E are logged into dialogue group 2. FIG. It is also assumed that users A, B, and D have logged into dialogue group 3 . In this case, the control unit 22 identifies the dialogue group 3 logged in by the user B as another dialogue group, and the display control unit 24 changes the screen 34 to a screen for dialogue with the dialogue group 3 . When an operation for changing the screen is detected while the screen for interacting with the dialogue group 3 is being displayed, the display control unit 24 displays the screen for interacting with the dialogue group 3 as the dialogue group 2. changes to screen 52 for interacting with .

According to Modified Example 7, the user can interact with another interactive group to which the user logged in to the current interactive group is logged in by a simple operation.

Further, the control unit 22 may determine priority based on the number of common users who are logged in, and the display control unit 24 may change the screen according to the priority. For example, an interaction group with a higher number of users in common who are logged in has a higher priority. A specific example will be given for explanation. Assume that user A is logged into dialogue groups 1, 7, and 8. Users A, B, and C are logged into dialogue group 1, users A, B, and D are logged into dialogue group 7, and users A, B, C, and E are logged into dialogue group 8. is logged in. In this case, except for user A, the number of common users between dialogue groups 1 and 7 is "1" (user B is the common user), and between dialogue groups 1 and 8 The number of common users is "2" (users B and C are common users). Therefore, the priority of the dialogue group 8 is first, the priority of the dialogue group 7 is second, and the display control unit 24 changes the screen in the order of the dialogue groups 8 and 7 . That is, in the above example, the screens are changed in the order of dialog groups 1, 8, and 7. FIG.

As in Modification 4, the priority may be changed according to the operation. Further, when a specific change operation is detected, the control unit 22 identifies the dialogue group in which the user A is logged in and has the largest number of common users, and the display control unit 24 causes the currently displayed The middle screen may be changed to a screen for interacting with that interaction group. When a change operation other than a specific change operation is detected, the display control unit 24 changes the screen according to the priority order. By doing so, the user can interact with the dialog group having the largest number of common users by a simple operation.

At least one of Modifications 3, 4, 5, and 6 and Modification 7 may be combined.

(Modification 8)
In Modified Example 8, the control unit 22 identifies the dialogue group with which the user A has been interacting until recently, and the display control unit 24 changes the currently displayed screen to a screen for interacting with the dialogue group. . By doing so, it is possible to have a dialogue with the nearest dialogue group by a simple operation.

(Modification 9)
In Modified Example 9, the control unit 22 duplicates and transcribes (copy and paste) statement content between a plurality of dialogue groups. The statement content may be statement content transmitted by the user himself or may be statement content transmitted by another user.

Modification 9 will be described in detail below with reference to FIGS. 10 and 11. FIG. Screen 34 of dialogue group 1 is shown in FIG. 10, and screen 52 of dialogue group 2 is shown in FIG. For example, when the user A designates the speech content 42 of the user B on the screen 34 of the dialogue group 1 being displayed and performs a copy operation to another dialogue group that is not being displayed, the control unit 22 The contents 42 are copied and pasted as user A's remark contents on the screen of the other dialogue group (for example, the screen 52 of the dialogue group 2) which is not displayed. The copy operation is, for example, an operation of sliding the statement content 42 in the direction indicated by the arrow 74 . When the user A slides the statement content to be copied to the outside of the screen 34, the statement content may be pasted on the screen of another dialogue group. On the screen 52 shown in FIG. 11, the copied statement content 42 is added as user A's statement content 76 . The statement content 76 is transmitted to the terminal devices 10 of users D and E who are logging in to the dialogue group 2 . Note that the statement content 76 may be transmitted to the terminal devices 10 of the users D and E when the copy operation is performed, and the statement content 76 may be transmitted when the operation to change the screen 34 to the screen 52 is detected. may be transmitted to the terminal devices 10 of the users D and E.

When an operation for changing the dialogue group is detected, the display control unit 24 changes the currently displayed screen (for example, screen 34) to a screen for dialogue with another dialogue group (for example, a copied and pasted The display is changed to the screen 52) on which the content of the statement is displayed.

According to Modification 9, it is possible to copy and paste statement contents between a plurality of dialogue groups with a simple operation.

Note that when the user A stops the copy operation within the copy source screen 34 (for example, when he stops touching the screen 34), the control unit 22 does not copy.

(Modification 10)
In Modified Example 10, the control unit 22 adds a user logged in to a dialogue group to another dialogue group. For example, the control unit 22 adds users included in the displayed dialogue group to the hidden dialogue group.

Modification 10 will be described in detail below with reference to FIGS. 12 and 13. FIG. FIG. 12 shows screen 34 of dialogue group 1, and FIG. 13 shows screen 52 of dialogue group 2. FIG. For example, when user A designates an image 38 associated with user B on the screen 34 of dialogue group 1 being displayed and performs an operation to add it to another dialogue group that is not being displayed, the control unit 22 Add user B to the other hidden dialogue group (eg, dialogue group 2). The adding operation is, for example, an operation of sliding the image 38 in the direction indicated by the arrow 78 . When the user A slides the image of the user to be added to the outside of the screen 34, the user to be added may be added to another dialogue group. An image 38 associated with User B is displayed on the screen 52 shown in FIG. In other words, user B has logged into dialogue group 2 .

When an operation for changing the dialogue group is detected, the display control unit 24 changes the currently displayed screen (for example, screen 34) to a screen for dialogue with another dialogue group (for example, user B is added). screen 52) of dialog group 2.

According to Modification 10, a user logged in to a certain dialogue group can be added to another dialogue group by a simple operation.

In addition, when the user A stops the addition operation within the screen 34 of the addition source (for example, when the user stops touching the screen 34, or when the image of the user to be added is displayed in a specific display area within the screen 34 are arranged), the control unit 22 does not add the user.

In Modified Example 10, when the approval of the logged-in user is obtained for the dialog group to which another user is added, the other user is added to the dialog group, and when the approval is not obtained, the other user is added to the dialog group. users may not be added to the dialogue group. For example, when user A performs an operation to add user B who is logged in to dialogue group 1 to dialogue group 2, terminal device 10A sends user D's terminal device 10D and user E's terminal device 10E an approval Submit your request. In this case, as shown in FIG. 14, an approval screen 80 is displayed on the UI units 16 of the terminal devices 10D and 10E. Is displayed. When user D approves user B's participation (for example, when user D presses the "Yes" button on the approval screen 80), terminal device 10D transmits information indicating approval to terminal devices 10A and 10B. Send. When user D does not approve user B's participation (for example, when the user presses the "No" button on the approval screen 80), terminal device 10D transmits information indicating disapproval to terminal devices 10A and 10B. do. User E is also the same.

User B is added to dialogue group 2 if approval is obtained by all users (eg, users D, E). Otherwise, user B will not be added to dialogue group 2 . As another example, when approval is obtained by a predetermined number or more of users, or when approval is obtained by a specific user (for example, a user with approval authority), user B may join dialogue group 2. may be added.

By requiring approval as described above, it is possible to reflect the intention of the logged-in user in the dialog group to which the user is added.

In addition, user B may be added to dialogue group 2 when user B to be added approves participation, and user B may not be added to dialogue group 2 when user B does not approve participation. For example, the terminal device 10A transmits a participation request to the user B's terminal device 10B. In this case, as shown in FIG. 15, an invitation screen 84 is displayed on the UI unit 16 of the terminal device 10B. 86 is displayed. When user B wishes to participate in dialogue group 2 (for example, when user B presses the "Yes" button on the invitation screen 84), terminal device 10B transmits information indicating participation to terminal device 10A. Send. When user B does not wish to participate in dialogue group 2 (for example, when user B presses the "No" button on the invitation screen 84), terminal device 10B sends information indicating that it will not participate to terminal device 10A. Send.

If user B wishes to join dialogue group 2, user B is added to dialogue group 2; If user B does not wish to participate in dialogue group 2, user B will not be added to dialogue group 2. By doing so, it is possible to reflect the intention of the user to be added.

Further, when the approval of the users logged in to the dialogue group to be added (for example, users D and E) is obtained and the user to be added (for example, user B) wishes to participate, the user to be added is May be added to a dialogue group.

(Modification 11)
In Modified Example 11, the control unit 22 changes the dialogue group to be changed according to the mode of the user's operation. The manner of operation is determined by, for example, at least one of the direction of operation, the speed of operation, and the number of times of operation.

Modification 11 will be described in detail below with reference to FIG. 16 . FIG. 16 shows screen 34 of dialog group 1 . A flick operation in each direction is associated with another dialogue group in which user A is logged in. The correspondence between each flick operation and the dialogue group is shown below.
- One flick operation in the direction indicated by the arrow 88 (to the right of the screen 34): dialogue group 2
- One flick operation in the direction indicated by the arrow 90 (to the left of the screen 34): dialogue group 3
・One flick operation in the direction indicated by the arrow 92 (upward direction of the screen 34): dialogue group 4
・One flick operation in the direction indicated by the arrow 94 (upper right direction of the screen 34): dialogue group 5
・One flick operation in the direction indicated by the arrow 96 (upper left direction of the screen 34): dialogue group 6
・One flick operation in the direction indicated by the arrow 98 (diagonally downward to the left of the screen 34): dialogue group 7
・One flick operation in the direction indicated by the arrow 100 (diagonally downward to the right of the screen 34): dialogue group 8
・One flick operation in the direction indicated by the arrow 102 (downward direction of the screen 34): dialogue group 9
・Flick operation twice in succession in the direction indicated by arrow 104 (to the right of screen 34): Dialogue group 10
・One fast flick operation in the direction indicated by the arrow 106 (to the right of the screen 34): dialogue group 11

Each flick operation will be described in more detail. The flick operation indicated by arrows 88 to 102 is one flick operation within a predetermined normal speed range. The flick operation indicated by the arrow 104 is an operation in which two flick operations within the normal speed range are performed in succession. For example, when the time interval between two flick operations is within a predetermined period of time, it is detected that two flick operations are continuously performed. The flick operation indicated by arrow 106 is a single flick operation faster than the normal speed range described above.

For example, when one flick operation within the normal speed range is performed in the direction indicated by the arrow 88 and the flick operation is detected, the display control unit 24 displays the screen 34 of the dialogue group 1 instead of The screen 52 of dialogue group 2 is displayed on the display unit. Further, when two flick operations within the normal speed range are continuously performed in the direction indicated by the arrow 104 and the continuous flick operations are detected, the display control unit 24 displays the screen 34 of the dialogue group 1. , the screen of the dialog group 10 is displayed on the display unit. Further, when a single flick operation faster than the normal speed range is performed in the direction indicated by the arrow 106 and the flick operation is detected, the display control unit 24 displays the screen 34 of the dialogue group 1 instead of the screen 34. , causes the screen of the dialog group 11 to be displayed on the display unit. Also when a flick operation in another direction is detected, the screen being displayed is changed to a screen for interacting with the dialogue group associated with the flick operation.

On the screen after change, the dialogue group 1 before change is associated with the flick operation in the direction associated with the dialogue group after change. For example, when the flick operation indicated by the arrow 88 is performed on the screen 34 , the screen 52 of the dialogue group 2 is displayed instead of the screen 34 . In this case, dialogue group 1 is associated with one flick operation in the direction indicated by arrow 88 . When the flick operation indicated by the arrow 88 is performed on the screen 52 , the screen 34 of the dialogue group 1 is displayed instead of the screen 52 . Of course, an operation and a dialogue group may be associated with each screen for each dialogue group.

The above associations are merely examples, and other associations may be made, or associations may be made by the user. For example, the direction, speed, number of times, etc. of the operation may be set by the user, and the user may associate the operation mode with the dialogue group.

According to Modification 11, since the dialogue group can be changed according to the operation mode, the dialogue group can be changed with a simple operation.

Note that the flick operation described above is merely an example of an operation for changing the dialogue group, and the dialogue group may be changed by an operation (gesture motion or voice) other than the flick operation. Also, a dialogue group may be associated with a combination of the user's gesture motion and voice.

In Modified Example 11, the display control unit 24 may cause the display unit to display information indicating the correspondence relationship between the operation mode and the dialogue group. For example, user A is logged into dialogue groups 1, 2, 3, and 4, and the current dialogue group is dialogue group 1. In this case, the display control unit 24 causes the display unit to display the screen 34 of the dialogue group 1, as shown in FIG. As in the example shown in FIG. 4 , the display control unit 24 causes the screen 34 to display an image and dialogue content associated with each user logged in to the dialogue group 1, and further displays the dialogue groups 2, 3, and 4. is displayed on the screen 34. For example, the dialog group 2 is linked to the right side of the screen 34, the dialog group 3 is linked to the left side of the screen 34, and the dialog group 4 is linked to the upper side of the screen 34. and In this case, the display control unit 24 causes the information 108 indicating the dialogue group 2 to be displayed on the right side of the screen 34, the information 110 indicating the dialogue group 3 to be displayed on the left side of the screen 34, and the information 112 indicating the dialogue group 4 to be displayed on the screen. 34 is displayed above. Information indicating a dialogue group is, for example, a character string or an image indicating the dialogue group. When the user A performs a right flick operation on the screen 34 and the flick operation is detected, the display control unit 24 causes the screen 52 of the dialogue group 2 to be displayed on the display unit instead of the screen 34 . By displaying the information indicating the correspondence between the operation mode (for example, the operation direction) and the dialogue group, it is possible to obtain visual information indicating which dialogue group can be interacted with by what kind of operation. , is given to the user.

Note that the information 108 and the like indicating the dialogue group may always be displayed on the screen 34, or may be displayed according to the user's instruction. For example, when the user performs a specific operation and the specific operation is detected, the display control unit 24 displays the information 108 or the like indicating the dialogue group within a predetermined time period or when another operation is detected. It may be displayed on the screen 34 until it is displayed. The specific operation is, for example, an operation (long-press operation) of pressing a portion of the screen 34 where an image associated with the user or dialogue content is not displayed for a predetermined period of time or longer. Of course, another operation may be defined as the specific operation. Also, the information 108 and the like may be displayed in a translucent state during display.

FIG. 18 shows another example of information indicating correspondence. In this example, the display control unit 24 causes the screen 34 of the dialog group 1 to display the map image 114 . The map image 114 is an image showing the correspondence between the operation directions and the dialogue groups. The numerical value displayed in the map image 114 indicates the number of the dialogue group, and the display position of the numerical value indicates the operation direction associated with the dialogue group. For example, the number "2" indicates dialogue group two. Since the numerical value "2" is displayed on the right side of the map image 114, the dialog group 2 is associated with the operation in the right direction. Therefore, when the user A performs an operation (for example, a flick operation) in the right direction on the screen 34 and the operation is detected, the display control unit 24 displays the screen 52 of the dialogue group 2 instead of the screen 34. displayed in the department. By displaying such a map image 114, the user is provided with visual information indicating which interaction group can be interacted with by what kind of operation.

As in the example shown in FIG. 17, the map image 114 may be always displayed on the screen 34, or may be displayed according to the user's instruction. For example, the display control unit 24 may display the map image 114 on the screen 34 when a specific operation by the user is detected. Further, when the screen 34 is changed to the screen of another dialogue group while the map image 114 is being displayed, or when another user is moved to another dialogue group, the display control unit 24 , the map image 114 may be hidden. By doing so, the map image 114 is hidden when the user's operation is completed, so it is possible to avoid a situation in which the display of the map image 114 makes it difficult for the user to see the content of the statement. Of course, the display control unit 24 may display the map image 114 until the user gives a non-display instruction. Also, the map image 114 may be displayed in a translucent state during display.

FIG. 19 shows yet another example of correspondence. In the example shown in FIG. 19, the display control unit 24 displays images 116 to 130 indicating the correspondence relationship between the operation direction and the dialogue group on the edge of the screen 34 . The numerical value displayed in each image indicates the number of the dialogue group, and the display position of the image indicates the operation direction associated with the dialogue group. For example, the number "2" indicates dialogue group two. Since the image 116 representing the numerical value "2" is displayed on the right edge of the screen 34, the interaction group 2 is associated with the operation to the right. Therefore, when the user A performs an operation (for example, a flick operation) in the right direction on the screen 34 and the operation is detected, the display control unit 24 displays the screen 52 of the dialogue group 2 instead of the screen 34. displayed in the department. By displaying the image indicating the dialogue group at the edge of the screen in this manner, the image is less likely to be superimposed on the speech content, and the speech content is less likely to be blocked by the image. Of course, the display control unit 24 grasps the position and size of the display content, and arranges the image showing the dialogue group on the screen 34 so as to avoid the image associated with the user and the display portion of the utterance content of each user. You may At that time, the display control unit 24 may realize the above arrangement by reducing the image associated with the user and the content of each user's statement. Alternatively, the display control unit 24 may display a reduced image showing the correspondence between the operation direction and the dialogue group on the screen 34 . By doing so, it is possible to display the image showing the correspondence between the operation direction and the dialogue group without degrading the visibility. Similar to the map image 114 shown in FIG. 18, when the screen 34 is changed to the screen of another dialogue group, or when another user is moved to another dialogue group, the display control unit 24 may hide images 116-130. Of course, the display control unit 24 may display the images 116 to 130 until the user gives a non-display instruction. Also, the images 116-130 may be displayed in a translucent state during display. By doing so, even if the images 116 to 130 are displayed overlapping the images associated with the user and the display portion of the utterance contents of each user, it is possible to prevent the visibility of each image and the utterance contents from being deteriorated. .

<Second embodiment>
An information processing system according to the second embodiment will be described below. An information processing system according to the second embodiment has the same configuration as the information processing system according to the first embodiment. A server 12 according to the second embodiment has the same configuration as the server 12 according to the first embodiment, and has a function of providing an SNS as in the first embodiment. Further, the terminal device 10 according to the second embodiment has the same configuration as the terminal device 10 according to the first embodiment, but the function of the display control unit 24 is the same as the function of the display control unit 24 according to the first embodiment. different. Below, processing of the display control unit 24 according to the second embodiment will be mainly described in detail.

Also in the second embodiment, as in the first embodiment, when an SNS is used, the display control unit 24 displays information (character strings, images, etc.) transmitted or received using the SNS, Displayed on the display unit of the UI unit 16 . In the second embodiment, when the user logs in to multiple dialogue groups, the display control unit 24 displays the dialogue contents of the multiple dialogue groups on the same screen.

Hereinafter, the operation of the terminal device 10 according to the second embodiment will be described in detail with specific examples.

For example, users A, B, and C belong to dialogue group 1, users A, D, and E belong to dialogue group 2, and dialogue groups 1 and 2 are both engaged in dialogue using SNS. shall be For example, assume that users A, B, and C have logged into dialogue group 1 and are sending and receiving messages, and users A, D, and E have logged into dialogue group 2 and are sending and receiving messages.

A screen displayed on the terminal device 10 when using the SNS will be described with reference to FIG. 20 . FIG. 20 shows an example of a screen displayed on the terminal device 10A used by the user A. As shown in FIG. The display control unit 24 of the terminal device 10A causes the display unit of the UI unit 16 to display a screen 132, and causes the screen 132 to display various information. The screen 132 is an interface (dialogue screen) for interacting with other users (speakers). Information (for example, character strings, images, etc.) input by each user is displayed on the screen 132 . The dialogue between multiple users may be a so-called chat-type dialogue (that is, a real-time dialogue, in other words, a dialogue progressing while each user speaks). For example, when the control unit 22 of the terminal device 10A executes the SNS application program, the display control unit 24 causes the display unit of the UI unit 16 to display a screen for interacting using the SNS. By executing the SNS application program, it may be possible to use an Internet telephone function, etc., in addition to the chat function.

For example, assume that user A is logged into dialogue groups 1 and 2 . In this case, the display control unit 24 causes the dialog content of the dialog group 1 and the dialog content of the dialog group 2 to be displayed on the same screen 132 . For example, the display control unit 24 sets display areas 136 and 138 in the horizontal direction (right and left) within the screen 132 with the virtual line 134 as a boundary, and displays the dialogue content of the dialogue group 1 in the display area 136. to display the dialogue contents of the dialogue group 2 in the display area 138 . In the display area 136, the contents of the dialogue among the users A, B, and C logged in to the dialogue group 1 are displayed. In the display area 138, the contents of the dialogue between the users A, D, and E who have logged in to the dialogue group 2 are displayed. If user A is logged into two interaction groups, virtual line 134 is set to the horizontal center of screen 132, for example. Of course, the display control unit 24 may control the size of each display area by changing the position of the virtual line 134 according to the length of the statement content (for example, message) in each dialogue group. For example, the display control unit 24 may change the position of the virtual line 134 so that the display area of the dialogue group with long speech content is wider than the display area of the dialogue group with short speech content. Further, the display control unit 24 may change the position of the virtual line 134 according to the amount of speech content. The display control unit 24 may change the position of the virtual line 134 according to the user's operation. Note that the display control unit 24 may or may not display the virtual line 134 on the screen 132 .

Although the dialogue contents of two dialogue groups are displayed on the same screen 132 in the example shown in FIG. 20 , the dialogue contents of three or more dialogue groups may be displayed on the same screen 132 . For example, when user A logs in to three or more dialogue groups, the dialogue contents of the three or more dialogue groups are displayed on the same screen 132 . Of course, if the user A is logged into one dialogue group (for example, dialogue group 1), the dialogue content of that one dialogue group (for example, dialogue group 1) is displayed as shown in FIG.

For example, when user A is logged in to one dialogue group (for example, dialogue group 1), the display control unit 24 displays a screen 34 for dialogue with dialogue group 1 on the display unit, as shown in FIG. Let In this situation, when user A logs in to yet another dialogue group (for example, dialogue group 2), the display control unit 24 expands the screen for dialogue, for example, and displays dialogue groups 1, 1, and 2 on the screen 132, for example. Display the contents of the dialogue of 2.

As another example, when user A is logged in to one dialogue group (for example, dialogue group 1), the display control unit 24 uses the screen in a vertically long state, as shown in FIG. Display the dialogue contents of the dialogue group 1 on the screen. When user A logs in to yet another dialogue group (for example, dialogue group 2), the display control unit 24 changes the screen from the vertically long state to the horizontally long state, and displays dialogue groups 1 and 2 on the horizontally long screen 132 . to display the contents of the dialog. In the example shown in FIG. 20, the content of dialogues of the dialogue groups 1 and 2 is displayed on the horizontally long screen 132 .

Further, the display control unit 24 may reduce each dialogue content (character string, image, etc.) and display it on the screen as the dialogue content of more dialogue groups is displayed.

Information displayed in each display area will be described in detail below.

The display control unit 24 causes the image 140 associated with the user A, the image 142 associated with the user B, and the image 144 associated with the user C to be displayed in the display area 136 assigned to the dialogue group 1 . An image 140 is an image for identifying user A, an image 142 is an image for identifying user B, and an image 144 is an image for identifying user C. FIG. Note that a character string indicating user A (for example, a character string for identifying user A such as name, user ID, handle name, nickname, etc.) may be displayed instead of image 140 or together with image 140 . . The same is true for images 142 and 144 . An image 140 associated with user A is displayed in a display area 136 assigned to user A who uses the terminal device 10A, and an image 142 associated with user B and an image 144 associated with user C are displayed. Within area 136, it is displayed in areas assigned to other users.

From then on, the users A, B, and C have a dialogue. Each user may input the utterance content by operating the UI unit 16 of his or her own terminal device 10 to input a character string, an image, or the like, or may input the utterance content by voice. Also, the content of each user's utterance may be output as voice. Each statement is displayed in chronological order according to the date and time when it was sent. As the dialogue progresses on the display area 136, the display area 136 scrolls, the past utterance contents that cannot be displayed in the display area 136 disappear from the display area 136, and the latest utterance contents and the most recent utterance contents are displayed. It is displayed in area 136 .

The utterance content 146 is the utterance content (for example, a message) transmitted by the user B using the terminal device 10B, and is displayed in the display area 136 in association with the user B image 142 . The utterance content 146 is also displayed as user B's utterance content on the terminal devices 10B and 10C. The utterance content 148 is the utterance content transmitted by the user A using the terminal device 10A, and is displayed in the display area 136 in association with the image 140 of the user A. is displayed as the content of the statement. The utterance content 150 is the utterance content transmitted by the user C using the terminal device 10C, and is displayed in the display area 136 in association with the image 144 of the user C. is displayed as the content of the statement. The utterance content 152 is the utterance content transmitted by the user A. FIG. In the example shown in FIG. 20, each statement content is transmitted in the order of statement content 146, 148, 150, 152, and the statement content 146, 148, 150, 152 is displayed in chronological order according to the transmitted date and time. be done. The same applies to the contents of the subsequent statements.

Also, as in the first embodiment, the display area 136 may display information indicating the time (for example, time or date) when each statement content was transmitted. For example, display area 136 displays a character string indicating a date (for example, today's date, November 2nd). Messages displayed below the display position of the character string indicating that date are messages sent on or after that date, and messages displayed above that display position are those sent on that date. This is the statement content sent on the date before. Of course, the information indicating the time and date may not be displayed.

Further, as in the first embodiment, read and unread message contents may be managed. The definitions of read messages and unread messages are the same as those according to the first embodiment.

In addition, the display control unit 24 causes the image 140 associated with the user A, the image 154 associated with the user D, and the image 156 associated with the user E to be displayed in the display area 138 assigned to the dialogue group 2 . An image 154 is an image for identifying user D, and an image 156 is an image for identifying user E. FIG. Note that, similarly to the display area 136, a character string indicating the user may be displayed instead of or together with the image of the user. The image 140 associated with the user A is displayed in the area assigned to the user A who uses the terminal device 10A within the display area 138, and the image 154 associated with the user D and the image 156 associated with the user E are displayed. Within area 138, it is displayed in areas assigned to other users.

After that, the users A, D, and E have a dialogue. The utterance content of each user is transmitted from the user's own terminal device 10 to the terminal device 10 of another user logged in to the dialogue group 2 and displayed. For example, user D's statement 158 is displayed in display area 138 in association with user D's image 154, user A's statement 160 is displayed in display area 138 in association with user A's image 140, User E's statement content 162 is displayed in display area 138 in association with user E's image 156 , and user A's statement content 164 is displayed in display area 138 in association with user A's image 140 . As in the display area 136, each message is displayed in chronological order according to the date and time when it was sent.

Similar to the display area 136, the display area 138 may also display information indicating the time (for example, time or date) when each message was transmitted. For example, the display area 138 displays a character string indicating a date (for example, yesterday's date, November 1st). Messages displayed below the display position of the character string indicating that date are messages sent on or after that date, and messages displayed above that display position are those sent on that date. This is the statement content sent on the date before. Of course, the information indicating the time and date may not be displayed.

Also in the dialogue group 2, as in the dialogue group 1, read and unread message contents may be managed.

On screen 132, user A can send message contents to dialogue groups 1 and 2. FIG. In other words, it is in a state in which it is possible to transmit the contents of statements to the dialogue groups 1 and 2 . For example, user A selects a destination dialogue group using the UI unit 16 and inputs the content of the statement. As a result, the content of the statement is transmitted to the destination dialogue group. For example, when the user A designates the display area 136 and inputs the content of the statement, the content of the statement is sent to the dialogue group 1 . The designation of the display area is performed, for example, by a touch operation on the display area or by voice. After inputting the statement, user A may designate a dialogue group to which the statement is sent. For example, user A may specify a destination dialogue group by performing a flick operation or the like. In this case as well, the content of the statement is sent to the destination dialogue group.

As described above, according to the second embodiment, it is possible to display and interact with a plurality of dialogue groups on the same screen. For example, multiple dialogue groups can be displayed and interacted with without expanding the display area, increasing the number of display units, or utilizing multiple screens.

Modifications of the second embodiment will be described below.

(Modification 12)
In modification 12, the display control unit 24 causes the display unit to display the dialogue content of the dialogue group in the active state, and does not display the dialogue content of the inactive dialogue group on the display unit. When there are a plurality of active dialogue groups, the display control unit 24 displays the dialogue contents of the plurality of dialogue groups on the same screen.

An active dialogue group is, for example, a dialogue group in which another user is logged in, a dialogue group in which the elapsed time from the transmission/reception of the last message is within a predetermined period of time, or the like.

For example, if the user A has logged in to dialogue groups 1 and 2, and the dialogue groups 1 and 2 correspond to the active dialogue groups, the display control unit 24 displays the dialogue groups as shown in FIG. 1 and 2 are displayed on the same screen 132 .

The display control unit 24 excludes the inactive dialogue group (the dialogue group that is not the active dialogue group) from the display targets. The display control unit 24 causes the display unit to display the dialogue content of the inactive dialogue group when a specific operation by the user (an operation indicating an instruction to display the dialogue content of the inactive dialogue group) is detected. may In this case, the display control unit 24 may display both the dialog content of the active dialog group and the dialog content of the inactive dialog group on the same screen, or display the dialog content of the active dialog group. The dialogue content of the inactive dialogue group may be displayed on the display instead of being displayed on the display.

An active dialogue group is inferred to be more likely to be interacted with by a user than an inactive dialogue group. Therefore, according to the modification 12, dialogue groups with which the user can interact are preferentially displayed.

(Modification 13)
In Modified Example 13, the display control unit 24 controls the display of each statement content so that the user who issued the statement content included in the dialogue content of the dialogue group can be identified. For example, the display control unit 24 displays the contents of remarks in different colors for each user. Hereinafter, modification 13 will be described in detail with reference to FIG. 21 . A screen 132 is shown in FIG.

Here, dialogue group 1 will be described. As in the example shown in FIG. 20 , the display control unit 24 causes user B's statement content 166 , user A's statement content 168 and 172 , and user C's statement content 170 to be displayed in the display area 136 . At this time, the display control unit 24 makes the display colors of the utterance contents of the respective users different from each other.

In addition, the display control unit 24 may cause the display area 136 to display a character string for identifying the dialogue group 1 (for example, the character string “dialogue group 1”). In the example shown in FIG. 21, the character string “dialogue group 1” is displayed in the upper portion of display area 136 .

Further, the display control unit 24 may collectively display the information of each user logged in to the dialogue group 1 in the display area 136 . In the example shown in FIG. 21 , images 174 , 176 , and 178 linked to each user are collectively displayed in the upper part of the display area 136 as information of each user. An image 174 is an image associated with user A, an image 176 is an image associated with user B, and an image 178 is an image associated with user C. FIG. The display color of each image corresponds to the display color of the utterance content of each user. For example, the display color of the image 174 associated with user A is the same as the display color of user A's utterance contents 168 and 172 . The display color of the image 176 associated with User B is the same as the display color of User B's statement content 166 . The display color of the image 178 associated with User C is the same as the display color of User C's statement content 170 . By doing so, it becomes easy to visually understand whose statement content is the content of each statement.

It should be noted that when displaying each message content in different colors, the images 140, 142, and 144 associated with the user may not be displayed. This is because even if the images 140, 142, and 144 are not displayed, it is possible to identify whose utterance content is the utterance content.

The display control unit 24 may change the display shape of each statement content with or without color-coding each statement content. Accordingly, the display control unit 24 may vary the display shapes of the images 174, 176, and 178 associated with each user. For example, the display control unit 24 makes the display shapes of the image and the statement content associated with the same user the same, and causes each image and each statement content to be displayed in the display area 136 .

In the example shown in FIG. 21, the above process is applied only to the dialogue group 1, but the above process may be applied to the dialogue group 2 as well.

(Modification 14)
In Modified Example 14, the display control unit 24 arranges each utterance content (e.g., message) included in the dialogue content of the same dialogue group on the same straight line and displays it in the display area assigned to the dialogue group. . Modification 14 will be described in detail below with reference to FIG.

Here, dialogue group 1 will be described. The display control unit 24 sets a virtual straight line 180 along the time-series direction in the display area 136 and arranges the statement contents 166 , 168 , 170 , and 172 on the straight line 180 . For example, the display control unit 24 arranges each utterance content such that the central portion of each utterance content is arranged on the straight line 180 . As a result, each utterance content has a symmetrical relationship with the straight line 180 as an axis of symmetry (left-right symmetry). By doing so, as shown in FIG. 20 , more space can be secured in the display area 136 compared to the case where the content of each user's remarks is displayed in the display area 136 by dividing it into left and right. . In other words, by arranging each utterance content closely along the straight line 180, it is possible to secure more space than when arranging each utterance content in a distributed manner. For example, the distance between the image 140 associated with the user A displayed at the position closest to the virtual line 134 that defines the display areas 136 and 138 and the virtual line 134 is a space (the space indicated by reference numeral 182). can be ensured. Further, as described in Modification 13 above, when the images 140, 142, and 144 associated with the user are not displayed, the statement content 172 displayed at the position closest to the virtual line 134 and the virtual line 134 A space (a space indicated by reference numeral 184) can be secured for the distance between them. The space may be used to increase the display area for other dialogue groups. For example, display area 136 for dialogue group 1 may be narrowed and display area 138 for dialogue group 2 may be widened to accommodate the space.

According to Modification 14, the limited display area can be effectively utilized.

The above arrangement example is merely an example, and another arrangement example may be employed. For example, the display control unit 24 may move each utterance content arranged on the straight line 180 to one edge (for example, the left edge of the screen 132) within the display area 136, One end of each display area may be aligned on a straight line.

In the example shown in FIG. 21, the above process is applied only to the dialogue group 1, but the above process may be applied to the dialogue group 2 as well.

In addition, the display control unit 24 may target a dialogue group with the shortest statement content among the plurality of dialogue groups, and arrange each statement content on the same straight line and display it in the display area. For example, the display control unit 24 compares the longest statement content (for example, the message with the largest number of characters) in the dialogue group 1 and the longest statement content in the dialogue group 2 . When the longest statement content in dialogue group 1 is shorter than the longest statement content in dialogue group 2 (for example, when the number of characters is less), display control unit 24 arranges each statement content in dialogue group 1 on the same straight line. do. By doing so, more space can be secured. Of course, the display control unit 24 may apply the processing according to Modification 14 to all dialogue groups.

(Modification 15)
In Modified Example 15, the display control unit 24 changes the display area of the dialogue content of another dialogue group in conjunction with the change of the display region of the dialogue content of a dialogue group included in the plurality of dialogue groups. For example, the display control unit 24 enlarges or reduces the display area of another dialogue group in conjunction with a user's operation (for example, enlargement operation or reduction operation) on the display area of a certain dialogue group. Modification 15 will be described in detail below with reference to FIG. 22 . A screen 132 is shown in FIG.

For example, when the screen 132 is displayed, the user performs an operation (for example, a pinch-out operation) to enlarge the display area 136 of the dialogue group 1 as indicated by an arrow 186, and if the operation is detected, The display control unit 24 enlarges the display area 136 . Along with this, the message content displayed in the display area 136 and the image associated with the user are enlarged and displayed. In addition, the display control unit 24 reduces the display area 138 of the dialogue group 2 in conjunction with the enlargement operation of the display area 136 by the amount of the enlargement. Along with this, the message content displayed in the display area 138 and the image associated with the user are reduced and displayed. The display control unit 24 displays on the same screen 132 the dialogue contents of the dialogue group 1 after expansion and the dialogue contents of the dialogue group 2 after reduction. In addition, when the user performs an operation of pinching the display area 136 (for example, a pinch-in operation) and the operation is detected, the display control unit 24 reduces the display area 136, interlocks with it, and creates a dialogue group. 2, the display area 138 is enlarged.

According to Modification 15, it is possible to enlarge or reduce the dialogue contents of some dialogue groups and display them in a limited display area.

Further, the display control unit 24 may enlarge the display area of the dialogue group in which the user A is inputting the content of the statement, and reduce the display areas of the other dialogue groups in conjunction with this. For example, when user A is inputting the content of a statement for dialogue group 1, display control unit 24 enlarges display area 136 for dialogue group 1 and reduces display area 138 for dialogue group 2. FIG. When the transmission of the statement content is completed, the display control unit 24 restores the size of the display area 136 to the size before enlargement, and restores the size of the display area 138 to the size before reduction. Further, when user A is inputting the contents of a statement to dialogue group 1, display control unit 24 may display display area 136 on the entire screen 132 and may not display display area 138 on screen 132 . That is, full-screen display of the display area 136 is performed. When the transmission of the statement content is completed, the display control unit 24 restores the sizes of the display areas 136 and 138 to their original sizes. The same is true when the speech content for dialogue group 2 is input.

Of course, when an enlargement operation or reduction operation is performed on the screen 132 , the display control unit 24 may enlarge or reduce the entire area of the screen 132 . The setting may be made by the user.

(Modification 16)
In modification 16, the display control unit 24 causes the display unit to display information (character strings, images, etc.) that cannot be displayed in the display area by scrolling the display area according to the user's operation. At this time, the display control unit 24 synchronizes scrolling of dialogue contents among the plurality of dialogue groups. That is, when a scrolling operation is performed on the display area of a certain dialogue group, the display control unit 24 scrolls the display area of the dialogue group, and furthermore, displays other dialogue groups displayed on the same screen. Scroll the area. Modification 16 will be described in detail below with reference to FIG.

A screen 132 is displayed in FIG. For example, when the user A performs an operation to scroll the display area 136 of the dialogue group 1 as indicated by an arrow 188 and the operation is detected, the display control unit 24 causes the display area to scroll in the direction indicated by the arrow 188. 136 is scrolled. In addition, the display control unit 24 scrolls the display area 138 of the dialogue group 2 in the same direction as the direction indicated by the arrow 188 as indicated by the arrow 190 . By doing so, the display area in which the scroll operation is not actually performed is also scrolled, saving the user the trouble of performing the scroll operation.

The amount of scrolling in the display area 136 in which the scrolling operation is actually performed may be the same as or different from the amount of scrolling in the display area 138 in which the scrolling operation is not performed. The setting may be made by the user.

Of course, the display control unit 24 may scroll the display area 136 in which the scroll operation is actually performed, and may not scroll the display area 138 in which the scroll operation is not performed without interlocking with the scroll operation. Interlocking control (synchronous control) or non-interlocking control (asynchronous control) may be set by the user.

If there is an unread message when the scroll operation is performed, the display control unit 24 may scroll the display area to the display position of the unread message. This processing will be described below with reference to FIG. A screen 132 is shown in FIG.

For example, when a scroll operation is performed on the display area 136 of the dialogue group 1, if there is an unread message in the dialogue group 1, the display control unit 24 moves the display area 136 to the display position of the unread message. scroll. For example, the display control unit 24 scrolls the display area 136 so that the unread message is displayed at a specific position (for example, central position, top, bottom, etc.) of the display area 136 . FIG. 24 shows the display area 136 after scrolling. For example, when user A's statement content 192 is in an unread state in dialogue group 1 , the display control unit 24 scrolls the display area 136 so that the statement content 192 is displayed at a specific position in the display area 136 . When there are a plurality of unread messages, the display control unit 24 may scroll the display area 136 to the display position of the unread message sent on the earliest date and time, or scroll the display position of the unread message sent on the latest date and time. You may scroll to the display position.

Further, when there is an unread message in dialogue group 2 for which no scroll operation has been performed, the display control unit 24 may scroll the display area 138 of dialogue group 2 to the display position of the unread message. FIG. 24 shows the display area 138 after scrolling. For example, when user A's statement content 194 is in an unread state in dialogue group 2 , the display control unit 24 scrolls the display area 138 so that the statement content 194 is displayed at a specific position in the display area 138 . The processing when there are multiple unread messages is the same as the processing described above for display area 136 .

By scrolling the display area to the display position of the unread message as described above, the user can save the trouble of searching for the unread message. Further, by scrolling to the display position of the unread message even in the display area where the scroll operation is not performed, the user's trouble of scroll operation can be saved.

(Modification 17)
In Modified Example 17, the control unit 22 duplicates and transcribes (copy and paste) statement content between a plurality of dialogue groups. The statement content may be statement content transmitted by the user himself or may be statement content transmitted by another user.

Modification 17 will be described in detail below with reference to FIG. 25 . A screen 132 is shown in FIG. For example, when the user A designates the speech content 146 of the user B on the display area 136 of the dialogue group 1 and performs a copy operation to the dialogue group 2, the control unit 22 copies the speech content 146 and copies the speech content 146 to the dialogue group. 2 display area 138 as user A's utterance content. A copy operation is, for example, an operation of sliding the statement content 146 in the direction indicated by an arrow 196 . When user A slides statement content 146 to be copied to display area 138 of dialog group 2 as a copy destination, control unit 22 may paste statement content 146 to display area 138 . In the example shown in FIG. 25, the copied statement content 146 is displayed in the display area 138 as user A's statement content 198 . The statement content 198 is transmitted to the terminal devices 10 of the users D and E who are logging in to the dialogue group 2 . Note that the message content 198 may be transmitted to the terminal devices 10 of the users D and E at the time when the copy operation is performed. It may be transmitted to the terminal device 10 of E.

According to Modified Example 17, it is possible to copy and paste statement contents between a plurality of dialogue groups with a simple operation.

Note that when the user A stops the copy operation within the copy source display area 136 (for example, stops touching the display area 136), the control unit 22 does not copy.

(Modification 18)
In Modified Example 18, the control unit 22 adds a user logged in to a dialogue group to another dialogue group.

Modification 18 will be described in detail below with reference to FIG. A screen 132 is shown in FIG. For example, when the user A designates the image 142 associated with the user B in the display area 136 of the dialogue group 1 and performs an addition operation to the dialogue group 2, the control unit 22 adds the user B to the dialogue group 2. do. The adding operation is, for example, an operation of sliding the image 142 in the direction indicated by the arrow 200 . When the user A slides the image 142 of the user B to be added to the display area 138 of the dialogue group 2 as the addition destination, the control unit 22 may add the user B to the dialogue group 2 . In the example shown in FIG. 26 , an image 142 associated with User B is displayed in the display area 138 of Dialogue Group 2 , and User B is thereby added to Dialogue Group 2 . In other words, user B has logged into dialogue group 2 .

According to Modification 18, a user logged in to a certain dialogue group can be added to another dialogue group by a simple operation.

It should be noted that when the user A stops the addition operation within the display area 136 of the addition source (for example, when the touch to the display area 136 is stopped, or when the addition target user's image), the control unit 22 does not add the user.

In Modified Example 18, when the approval of the user logged in to the dialogue group to which another user is added is obtained, the other user is added to the dialogue group, and when the approval is not obtained, the other user is added to the dialogue group. users may not be added to the dialogue group. For example, when user A performs an operation to add user B who is logged in to dialogue group 1 to dialogue group 2, terminal device 10A sends user D's terminal device 10D and user E's terminal device 10E an approval Submit your request. In this case, as in the first embodiment, an approval screen (for example, the approval screen 80 shown in FIG. 14) is displayed on the UI units 16 of the terminal devices 10D and 10E. A message will appear asking if you want to approve the When user D approves user B's participation (for example, when user D presses the "Yes" button on the approval screen), terminal device 10D transmits information indicating approval to terminal devices 10A and 10B. do. When user D does not approve user B's participation (for example, when the user presses the "No" button on the approval screen), terminal device 10D transmits information indicating disapproval to terminal devices 10A and 10B. . User E is also the same.

User B is added to dialogue group 2 if approval is obtained by all users (eg, users D, E). Otherwise, user B will not be added to dialogue group 2 . As another example, user B may be added to dialogue group 2 when approval is obtained by a predetermined number of users, or when approval is obtained by a specific user (eg, a user with approval authority). may be

By requiring approval as described above, it is possible to reflect the intention of the logged-in user in the dialog group to which the user is added.

In addition, user B may be added to dialogue group 2 when user B to be added approves participation, and user B may not be added to dialogue group 2 when user B does not approve participation. For example, the terminal device 10A transmits a participation request to the user B's terminal device 10B. In this case, as in the first embodiment, an invitation screen (for example, the invitation screen 84 shown in FIG. 15) is displayed on the UI unit 16 of the terminal device 10B. A message is displayed requesting user B's participation in the event. When user B wishes to participate in dialogue group 2 (for example, when user B presses the "Yes" button on the invitation screen), terminal device 10B transmits information indicating participation to terminal device 10A. do. When user B does not wish to participate in dialogue group 2 (for example, when user B presses the "No" button on the invitation screen), terminal device 10B transmits information indicating that it will not participate to terminal device 10A. do.

If user B wishes to join dialogue group 2, user B is added to dialogue group 2; If user B does not wish to participate in dialogue group 2, user B will not be added to dialogue group 2. By doing so, it is possible to reflect the intention of the user to be added.

Further, when the approval of the users logged in to the dialogue group to be added (for example, users D and E) is obtained and the user to be added (for example, user B) wishes to participate, the user to be added is May be added to a dialogue group.

(Modification 19)
In Modified Example 19, the display control unit 24 displays the dialogue contents of a plurality of dialogue groups on the same screen while arranging them in the vertical direction. Modification 19 will be described in detail below with reference to FIG. 27 . A screen 132 is shown in FIG.

The display control unit 24 uses the screen 132 in a vertically long state, and displays the dialogue contents of the dialogue groups 1 and 2 vertically arranged on the screen 132 . For example, the display control unit 24 sets display areas 204 and 206 in the vertical direction (up and down) on the screen 132 with the virtual line 202 as a boundary, and displays the dialogue content of the dialogue group 1 in the display area 204. to display the dialogue contents of the dialogue group 2 in the display area 206 . In the display area 204, the contents of the dialogue among the users A, B, and C logged in to the dialogue group 1 are displayed. In the display area 206, the contents of the dialogue among the users A, D, and E who have logged in to the dialogue group 2 are displayed. If user A is logged into two interaction groups, virtual line 202 is set to the vertical center of screen 132, for example. Of course, the display control unit 24 may control the size of each display area by changing the position of the virtual line 202 according to the length of the statement content in each dialogue group. For example, the display control unit 24 may change the position of the virtual line 202 so that the display area of the dialogue group with long speech content is wider than the display area of the dialogue group with short speech content. Further, the display control unit 24 may change the position of the virtual line 202 according to the amount of speech content. For example, the display control unit 24 may change the position of the virtual line 202 so that the display area of the dialogue group with more utterance content is wider than the display area of the dialogue group with less utterance content. The display control unit 24 may change the position of the virtual line 202 according to the user's operation. Note that the display control unit 24 may or may not display the virtual line 202 on the screen 132 .

Although the dialogue contents of two dialogue groups are displayed on the same screen 132 in the example shown in FIG. 27, the dialogue contents of three or more dialogue groups may be displayed on the same screen 132 .

For example, when user A logs in to one dialogue group (for example, dialogue group 1), the display control unit 24 displays the dialogue content of dialogue group 1 on the vertically long screen as shown in FIG. In this situation, when the user A logs in to yet another dialogue group (for example, dialogue group 2), the display control unit 24 displays the dialogue contents of the dialogue groups 1 and 2 vertically arranged side by side on the vertically long screen 132. .

Further, when the user A performs an operation to scroll the display area 204 of the dialogue group 1 as indicated by an arrow 208 and the operation is detected, the display control unit 24 scrolls the display area in the direction indicated by the arrow 208 . 204 is scrolled. Further, the display control unit 24 scrolls the display area 206 of the dialogue group 2 in the same direction as the direction indicated by the arrow 208 as indicated by the arrow 210 . By doing so, the display area in which the scroll operation is not actually performed is also scrolled, saving the user the trouble of performing the scroll operation.

Of course, the display control unit 24 may scroll the display area 204 in which the scroll operation is actually performed, and may not scroll the display area 206 in which the scroll operation is not performed without interlocking with the scroll operation. Interlocking control (synchronous control) or non-interlocking control (asynchronous control) may be set by the user.

In the example shown in FIG. 27, the transmission date and time of the statement content and the read information are not displayed, but they may be displayed.

Further, similarly to the 16th modification described above, the display control unit 24 may scroll the display area in which the scroll operation is performed to the display position of the unread message. The display control unit 24 may scroll the display area in which the scroll operation has not been performed to the display position of the unread message in conjunction with the scrolling of the display area in which the scroll operation has been performed.

Further, as in the twelfth modified example described above, the display control unit 24 causes the display unit to display the dialogue content of the dialogue group in the active state, and does not display the dialogue content of the inactive dialogue group on the display unit. good. As in the thirteenth modification described above, the display control unit 24 may color-code the content of each user's statement. As in Modification 15 above, the display control unit 24 may enlarge or reduce the display area of another dialogue group in conjunction with the enlargement or reduction of the display area of a certain dialogue group. As in Modification 17 above, the control unit 22 may copy and paste statement content between a plurality of dialogue groups. Similar to Modification 18 above, the control unit 22 may add a user logged in to a certain dialogue group to another dialogue group.

When inputting the contents of a statement (for example, a message), the display control unit 24 displays an input area 212 on the screen 132 as shown in FIG. When user A inputs a message in input area 212 and instructs transmission, the message input in input area 212 is transmitted to the dialogue group specified as the destination. For example, when transmitting statement content to dialogue group 1, user A designates display area 204 of dialogue group 1. FIG. The display control unit 24 displays the input area 212 on the screen 132 according to the designation. The display control unit 24 may display the input area 212 in the display area 204 of the dialogue group 1, or may display the input area 212 in the display area 206 of the dialogue group 2, which is not the destination of the message content. good. Further, the display control unit 24 may display the input area 212 on the screen 132 across the display areas 204 and 206 . The display position and display size of the input area 212 may be set by the user. When a message is input in the input area 212 and transmission of the message is completed, the display control unit 24 hides the input area 212 . Of course, after User A has entered a message in input area 212, User A may specify the interaction group to which the message should be sent. For example, when the user A moves the input area 212 to a certain display area by an operation such as a flick operation, the control unit 22 transmits a message to the dialogue group associated with that display area.

Further, the display control unit 24 may switch between the horizontally long screen (see FIG. 20) and the vertically long screen (see FIG. 27) according to the screen switching condition. The screen switching condition may be set by the user or may be determined in advance. For example, the display control unit 24 controls the overall size of the screen 132, the number of dialogue groups logged in by the user A, the number and length of utterances of each dialogue group per unit time, the number of unread messages per unit time, The number and length of recent messages (the time between the current time and a predetermined time before the current time), the number of most recent unread messages, the total number of messages, the total length of messages, and the number of unread messages The horizontally long screen and the vertically long screen may be switched according to conditions such as the total number. The display control unit 24 may switch screens according to a plurality of conditions. For example, the display control unit 24 uses the vertically long screen when the number of dialogue groups logged in by user A is equal to or greater than a predetermined threshold, and uses the horizontally long screen when the number is less than the threshold. You may Of course, the display control unit 24 may switch between the horizontally long screen and the vertically long screen according to the user's instruction.

(Modification 20)
In Modified Example 20, the display control unit 24 displays an input area for inputting statement content on the screen across display areas of a plurality of dialogue groups. When the transmission of the statement content is completed, the display control unit 24 hides the input area and displays the statement content in the display area of the destination dialogue group. Modification 20 will be described in detail below with reference to FIGS. 29 and 30. FIG. A screen 132 is shown in FIGS.

For example, when inputting the content of a statement (message), the display control unit 24 displays an input area 214 on the screen 132 as shown in FIG. At this time, the display control unit 24 displays the input area 214 on the screen 132 across the display area 136 of the dialogue group 1 and the display area 138 of the dialogue group 2 . When the user A inputs a message in the input area 214 and instructs transmission of the message, the message is transmitted to the terminal device 10 of the user logged in to the dialogue group designated as the transmission destination. The destination dialogue group may be specified before the input area 214 is displayed, or after the input area 214 is displayed. For example, when the user A designates the display area 136 of the dialogue group 1, the control unit 22 identifies the dialogue group 1 as the destination dialogue group, and the display control unit 24 displays the input area 214 on the screen 132. Let Subsequently, when the user A inputs a message in the input area 214 and gives a transmission instruction, the message is used as the message content of the user A, and the terminal devices of the users B and C logged in to the dialogue group 1 are displayed. 10. As another example, when the user A gives an instruction to display the input area 214 , the display control unit 24 displays the input area 214 on the screen 132 . Subsequently, when the user A inputs a message in the input area 214 and designates the destination dialogue group 1 to give a transmission instruction, the message is used as the statement contents of the user A and logged in to the dialogue group 1. are transmitted to the terminal devices 10 of the users B and C, respectively. For example, when user A moves the input area 214 into the display area 136 of the dialogue group 1 by a flick operation or the like, the control unit 22 transmits messages to the terminal devices 10 of users B and C, respectively.

When user A's message is transmitted, as shown in FIG. 30 , the message is displayed in display area 136 as user A's statement content 216 in association with user A's image 140 . When the transmission of the message is completed, the display control section 24 hides the input area 214 .

(Modification 21)
Modification 21 will be described with reference to FIGS. 31 and 32 . In the second embodiment described above, the dialogue contents of two dialogue groups are displayed on the same screen, but the dialogue contents of three or more dialogue groups may be displayed on the same screen. FIGS. 31 and 32 show display examples when the number of dialogue groups is four.

For example, when user A is logged in to four dialogue groups 1, 2, 3, and 4, the display control unit 24 divides the screen 132 into left and right virtual lines 218 and the screen 132 as shown in FIG. Four display areas (display areas 222, 224, 226, and 228) are set by setting a virtual line 220 that divides the display vertically. For example, the display control unit 24 displays the dialogue contents of the dialogue group 1 in the display area 222, displays the dialogue contents of the dialogue group 2 in the display area 224, and displays the dialogue contents of the dialogue group 3 in the display area 226. display, and display the dialogue contents of the dialogue group 4 in the display area 228 . The size of each display area may be the same, or the size of each display area may be different according to the number and length of utterances of each dialogue group. The size of each display area may be changed by the user, or when a certain display area is enlarged or reduced, other display areas may be enlarged or reduced accordingly.

FIG. 32 shows another display example. In this example, the display control unit 24 sets a virtual line 230 that divides the screen 132 into left and right, and virtual lines 232 and 234 that vertically divide the horizontal half (for example, the right half) of the screen into three areas. Four display areas (display areas 236, 238, 240, 242) are set. The display area 236 is larger than the other display areas, and the display areas 238, 240, 242 are areas having the same size. For example, display area 236 may be used as a main display area to display the interaction content of the main interaction group designated by the user. Display areas 238, 240, and 242 are used as sub-display areas to display the dialogue content of dialogue groups other than the main dialogue group.

The display control unit 24 may change the dialogue groups displayed in the main display area 236 according to priority. The order of priority is, for example, the number and length of messages of each dialogue group per unit time, the number of unread messages per unit time, the most recent time), the number of recent unread messages, the total number of messages, the total length of messages, the total number of unread messages, and the like. For example, the display control unit 24 may cause the display area 236 to display the dialogue content of the dialogue group with the largest number of recent statements, or display the dialogue content of the dialogue group with the longest recent statement length. The display area 236 may be displayed, or the dialogue content of the dialogue group with the most recent unread messages may be displayed in the display area 236 . In addition, the display control unit 24 may cause the display area 236 to display the dialogue content of the active dialogue group. Note that the display control unit 24 may change the size of each of the display areas 238, 240, and 242 according to the order of priority.

<Third Embodiment>
An information processing system and a terminal device 10 according to the third embodiment will be described below. In the third embodiment, the display control unit 24 switches between the display control according to the first embodiment and the display control according to the second embodiment according to a switching condition. In other words, the display control unit 24 switches between the screen showing the dialogue content of one dialogue group and the screen showing the dialogue content of a plurality of dialogue groups according to the switching condition. Processing according to switching conditions will be described in detail below.

For example, the display control unit 24 may switch display control according to the number of dialogue groups to which user A is logged in. Specifically, the display control unit 24 executes the display control according to the first embodiment when the number of dialogue groups logged in by the user A is equal to or greater than a predetermined threshold, and the number is less than the threshold. , the display control according to the second embodiment is executed. The threshold may be changed by the user.

For example, assume that the threshold is "3". When the user A has logged in to three or more dialogue groups (for example, dialogue groups 1, 2, and 3), the display control unit 24 executes display control according to the first embodiment. That is, the display control unit 24 changes the screen of the dialogue group being displayed to the screen of another dialogue group according to the change operation by the user. For example, when the screen of dialogue group 1 is displayed on the display unit and the user performs a change operation, the display control unit 24 changes the screen from the screen of dialogue group 1 to the screen of dialogue group 2. . On the other hand, when the user A is logged into two dialogue groups (for example, dialogue groups 1 and 2), the display control unit 24 executes display control according to the second embodiment. That is, the display control unit 24 displays the dialogue contents of the dialogue groups 1 and 2 on the same screen.

When displaying the dialogue contents of a plurality of dialogue groups on the same screen, as the number of dialogue groups increases, the display area of the dialogue contents of each dialogue group has to be narrowed, making it difficult for the user to see the dialogue contents. Become. On the other hand, the smaller the number of dialogue groups, the wider the display area for each dialogue content. Compared to the case where the contents are displayed on the same screen, it becomes easier for the user to see each dialogue contents. Therefore, when the number of dialogue groups is equal to or greater than a threshold value, the display control according to the first embodiment is executed to prevent the dialogue content of each dialogue group from becoming difficult for the user to see, and to perform the dialogue with a simple operation. , the screen of each dialogue group can be changed. Further, when the number of dialogue groups is less than the threshold, by executing the display control according to the second embodiment, the dialogue contents of a plurality of dialogue groups can be displayed in a state that is easy for the user to view while eliminating the need for the screen change operation. can be displayed.

Further, as a combination of the first embodiment and the second embodiment, the display control unit 24 displays a screen showing the dialogue contents of a plurality of dialogue groups according to a change operation by the user. The screen may be changed to display the content. This process will be described in detail with reference to FIGS. 33 and 34. FIG.

Screen 132 is shown in FIG. 33 and screen 244 is shown in FIG. For example, user A is logged into dialogue groups 1, 2, 3, and 4. Display areas 136 and 138 are defined on the screen 132 by a virtual line 134 . Similarly, screen 244 has display areas 248 and 250 defined by phantom lines 246 . As an example, the display area 136 is an area where the dialogue content of the dialogue group 1 is displayed, the display area 138 is an area where the dialogue content of the dialogue group 2 is displayed, and the display region 248 is an area where the dialogue content of the dialogue group 3 is displayed. The display area 250 is an area in which the dialogue contents of the dialogue group 4 are displayed. For example, the display control unit 24 may determine the display area in which the dialogue content of each dialogue group is displayed according to the order in which the user A logs into each dialogue group, or the user A may determine the display area of each dialogue group. may be specified, or the display area of each dialogue group may be determined according to the priority order described in Modification 21. The size of each display area may be changed by the user, determined according to priority, or determined in advance.

For example, while the screen 132 is being displayed on the display unit, if the user performs a change operation as in the first embodiment, the display control unit 24 changes the screen being displayed from the screen 132 to the screen 244. change. By doing so, the user A can interact with a plurality of dialogue groups without performing a screen change operation, and can further interact with a plurality of other dialogue groups by performing a simple screen change operation. can do.

<Other embodiments>
In the first embodiment, the screen may be changed gradually according to the user's change operation. This processing will be described below with reference to FIGS. 35 to 37. FIG. 35 to 37 show screens displayed on the terminal device 10. FIG.

For example, assume that user A is logged into dialogue groups 1 and 2 . In this case, as shown in FIGS. 35 to 37, the controller 22 forms a display area 252, sets a virtual line 254 in the display area 252, and sets display areas 256 and 258. FIG. The control unit 22 arranges the dialogue contents of the dialogue group 1 in the display area 256 and arranges the dialogue contents of the dialogue group 2 in the display area 258 . This arrangement state may be, for example, the same as the arrangement state of the dialogue content according to the second embodiment.

In the examples shown in FIGS. 35 to 37, the display area 252 is wider than the screen 260 of the terminal device 10. FIG. More specifically, the width of the display area 252 is wider than the width of the screen 260 . Therefore, the entire display area 252 cannot be displayed on the screen 260 at once. In the example shown in FIG. 35, the display area 256 of the dialogue group 1 is displayed on the screen 260, and the user A can interact with the users B and C logged in to the dialogue group 1. In the example shown in FIG. This display state is the same as the display state shown in FIG. Also, the display area 258 of the dialog group 2 is not displayed on the screen 260 .

In a state where the display area 256 is displayed on the screen 260, when the user A operates the screen 260 in the direction of the display area 258 of the dialogue group 2 (for example, flicks or slides in the direction indicated by the arrow 262). case), the display control unit 24 changes the part of the display area 252 displayed on the screen 260 according to the amount of operation. For example, as shown in FIG. 36, part of the display area 256 and part of the display area 258 are displayed on the screen 260 according to the amount of operation. Thus, display area 256 for dialogue group 1 and display area 258 for dialogue group 2 are displayed on screen 260 in succession.

When the user A further operates the screen 260 in the direction of the arrow 262, the display control unit 24 changes the part of the display area 252 displayed on the screen 260 according to the amount of operation. For example, as shown in FIG. 37, the entire display area 258 is displayed on the screen 260 according to the amount of operation. In this state, display area 256 is not displayed on screen 260 .

As described above, the display area of a certain dialogue group and the display area of another dialogue group may be connected, and the area displayed on the screen 260 may be continuously changed by the user's operation.
